FOREARM STABILIZER FOR SHOTGUN AND RIFLES Filed Dec. 4, 1964 2 Sheets-Sheet 2 United States Patent 3,242,608 FOREARM STABILIZER FOR SHOTGUN AND RIFLES Denzil Noble Heppard, 318 Illinois St., Vallejo, Calif. Filed Dec. 4, 1964, Ser. No. 415,948 3 Claims. (Cl. 42--71) This invention relates to pump action firearms and the like.

It is an object of the present invention to provide a forearm stabilizer which will stop lateral rolling of the forearm on rifles and shotguns.

Another object of the present invention is to provide a forearm stabilizer which will keep the forearm out of contact with the outside diameter of the magazine tube and also the barrel, eliminating wearing of the bluing of these components.

A further object of the present invention is to provide a forearm stabilizer of the above type which will smoothly operate and will operate with a minimum of effort.

Other objects of the invention are to provide a forearm stabilizer for rifles and shotguns bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efficient in operation and use.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawing, in which:

FIGURE 1 is a side view of the present invention showing the components removed from each other;

FIGURE 2 is an end view of the slide rail showing the gun barrel in phantom lines;

FIGURE 3 is an end view of the magazine shown in FIGURE 1;

FIGURE 4 is a right end view of the slide sleeve shown in FIGURE 1;

FIGURE 5 is a plan view of the locking ring shown in FIGURE 1;

FIGURE 6 is a plan view of the stabilizer ring shown in FIGURE 1;

FIGURE 7 is a left end view of the slide sleeve shown in FIGURE 1;

FIGURE 8 is an end view of the forearm handle shown in FIGURE 1;

FIGURE 9 is a side view of the present invention shown fully assembled; and

FIGURE 10 is a side view of the gun stock.

Referring now more in detail to the drawing, a forearm stabilizer 10 for pump action shotguns and rifles made in accordance with the present invention is shown to include an elongated slide rail 12 of inverted T-shaped configuration which is silver soldered beneath barrel 14 parallel to the longitudinal axis of barrel 14. A guide member 16 which is fixedly secured to a hollow slide sleeve 18 is freely and slidably received upon slide rail 12 and prevents lateral play of forearm handle 20. Slide sleeve 18 is received within forearm handle 20, and a locking ring 22 is received against stabilizer ring 24 and secures the forearm .assembly in the well known manner, slide sleeve 18 being provided with a flange 26 which abuts with the rear end of forearm 20. The fore end of magazine tube 28 is slidably received within slide sleeve 18 with a loose fit. The rear end of magazine tube 28 is received within tube 30 which extends from the forward end of firearm action 32.

In use, slide sleeve 18 being rigidly guided by guide 3,242,608 Patented Mar. 29, 1966 "ice member 16 secured thereto in conjunction with the slide rail 12 secured to barrel 14, prevents side play or lateral motion of the forearm handle 20 during the forward or rearward oscillation of forearm handle 20 to load, cock and eject shells from action 32.

It shall be noted that the heretofore described forearm stabilizer 10 serves to function smoothly from the full forward extreme to the full rearward extreme of forearm handle 20.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

1. In a repeating firearm having a receiver, a barrel, and a magazine tube for cartridges, the barrel and the magazine tube being mounted rigidly in spaced apart parallel arrangement on the receiver, and further having a forearm reciprocally moveable for transferring the cartridges from the magazine tube to the receiver, the forearm fitting loosely over the magazine tube; the combination of a slide rail secured to said barrel along a portion of the barrel and in the space between barrel and tube, and means secured to said forearm and engaging said slide rail with a free sliding fit throughout the reciprocating motion of said forearm thereby preventing lateral motion of said forearm with respect to said rigidly mounted barrel and tube during said reciprocation.

2. The combination defined in claim 1 wherein said forearm comprises a handle secured to an elongated slide sleeve, said slide rail has an irregular cross-section, and said slide rail engaging means comprises a member secured to said slide sleeve, said member having at least two surfaces interlocking with the cross-section of said slide rail, said surfaces being at spaced positions longitudinally of said slide sleeve.

3. In a repeating firearm having a receiver, a barrel, and a magazine tube for cartridges, the barrel and the magazine tube being mounted rigidly in spaced apart parallel arrangement on the receiver, and further having a slide sleeve reciprocally moveable for transferring the cartridges from the magazine tube to the receiver, the slide sleeve fitting loosely over the magazine tube; the combination of a slide rail secured to said barrel along a portion of the barrel and in the space between barrel and tube, said slide rail having an irregular cross-section; and an elongated guide member secured to the slide sleeve, said guide member having a cross-section shaped to mate with the cross-section of said slide rail and engaging said slide rail with a free sliding fit throughout the reciprocating motion of said slide sleeve, thereby preventing lateral motion of said slide sleeve with respect to the rigidly mounted barrel and tube during said reciprocation.
